The term “2.4L I4 F DOHC 16V” signifies a specific type of internal combustion engine notable for its configuration and capabilities. In this nomenclature, ‘2.4L’ refers to the engine’s total displacement, a measure of the total volume of all the cylinders combined—a key factor in an engine’s power potential. ‘I4’ indicates an inline-four engine where four cylinders are aligned in a single row, a layout common for its balance between power, efficiency, and smooth operation.
Engines with the ‘DOHC’ designation, which stands for Dual Overhead Camshaft, employ two camshafts per bank of cylinders—one camshaft operates the intake valves, and the other operates the exhaust valves. This setup typically allows for more precise valve timing, which can enhance both performance and fuel economy. The ’16V’ denotes that the engine has 16 valves in total, indicating that each of the four cylinders is equipped with four valves—two for intake and two for exhaust, improving the engine’s ability to ‘breathe’ and hence perform efficiently.
We understand these technical terms not only highlight the design but also hint at the performance characteristics of such engines. They are commonly found in a variety of vehicles, delivering a balance of power and efficiency that makes them suitable for daily commuting as well as demanding driving scenarios. Our collective experiences have proven the versatility of these engines, making them a favored choice in the automotive market for a broad range of applications.

Engine Innovations
In the realm of internal combustion engines, our 2.4L I4 F DOHC 16V engines stand as a testament to mechanical evolution and technological advancements. These powerplants benefit from a precision-engineered setup that optimizes fuel efficiency and power output, catering to the demands of modern driving.
Displacement and Structure: With a displacement of 2.4 liters, the engine offers a robust power base without encroaching on the efficiency territory. Our aluminum engine block and cylinder head contribute to weight reduction and improved thermal management, ensuring better performance and longevity.
DOHC and Valvetrain: The dual overhead camshaft (DOHC) setup permits optimal positioning of the valves for a more refined air flow, while the 16 valve configuration—with four valves per cylinder—maximizes combustion efficiency. The camshafts manipulate valves directly via a timing chain, a reliable method that typically extends service intervals.
permits dynamic control of valve operation to provide a harmony between power output, fuel consumption, and emissions throughout a wide range of engine speeds.
Fuel System: Beginning with the introduction of direct fuel injection (GDI), fuel is delivered more precisely into the combustion chamber, which increases the compression ratio without the abnormal combustion phenomena known as “knocking.” A high-pressure fuel pump, driven by the camshaft, has fortified our engines with increased fuel economy and power.
Compression Details
- Improved compression ratio benefits power and efficiency
- Advanced pistons designed to withstand higher pressures
- Optimized bore and stroke enhance performance
| Component | Specification | Benefit |
| Engine Block | Aluminum with cast iron liner | Lightweight and durable |
| Fuel System | Direct Injection | Efficient combustion |
| Valve System | DOHC with VVT | Enhanced engine breathing |
With each innovation, we’ve not only enhanced engine performance but also maintained a responsible attitude towards environmental care by systematically reducing emissions. Adhering to strict engineering principles and a commitment to quality, our 2.4L I4 F DOHC 16V engines continue to set benchmarks in automotive powertrain technology.
Efficiency and Performance
Engines with a Double Overhead Cam (DOHC) design permit higher valve angles, improving air and fuel flow within the cylinder. Here, the 16-valve architecture ensures more precise valve timing control, translating to improved power output and responsiveness. Coupled with direct injection, which enables more controlled and efficient fuel usage, we see a distinct improvement in overall engine performance.
Manufacturers like Honda have leveraged this technology to extract more power, with some engine variants producing up to 205 horsepower and 164 lb-ft of torque. This torque figure represents the engine’s rotational force and has a direct impact on acceleration.
Fuel economy varies across models and installations, but advancements in transmission systems, such as the CVT (Continuously Variable Transmission), have further enhanced these engines’ efficiency.
In terms of real-world applications, the Chevrolet Equinox with the 2.4L engine provides a practical example. It displays a judicious use of fuel while maintaining sufficient power for most driving situations, reflecting the engine’s design intention for a balance between efficiency and performance.
Model-Specific Features
When discussing the 2.4L I4 F DOHC 16V engine, we focus on specifics that make it unique in various models. For instance, Chevrolet’s Equinox and Malibu have come equipped with this engine, providing reliable performance and decent fuel efficiency.
The Equinox offers this engine across several trim levels, commonly paired with a six-speed automatic transmission, which enhances smooth shifting and driving experience. The Malibu, armed with the same 2.4-liter four-cylinder engine, stands out for its balance of power and economy, suitable for daily drives.
- Chevrolet Equinox: 6-speed automatic.
- Chevrolet Malibu: 6-speed automatic.
- Kia Optima: 6-speed manual or automatic.
- Hyundai Sonata: 6-speed manual or automatic.
- Buick Regal: 6-speed automatic (later models).
It’s important to address the oil consumption issue which has been observed in some models with the 2.4L engine, mainly due to wear on the piston rings. In addition, care should be taken with the tensioner to avoid premature wear.
The K24, famously known in the Honda models, must not be confused with General Motors’ or other manufacturers’ 2.4L engines, as the specifications and designs diverge significantly.
| Vehicle Model | Engine | Transmission |
| Chevrolet Equinox | 2.4L I4 F DOHC 16V | 6-speed automatic |
| Chevrolet Malibu | 2.4L I4 F DOHC 16V | 6-speed automatic |
Maintenance is crucial: regular checks on oil levels and timely replacement of the tensioner can prevent common issues associated with the 2.4L engine.
User Experience and Maintenance
When we discuss the user experience of vehicles with a 2.4L I4 F DOHC 16V engine, we focus on aspects like steering, interior comfort, and overall vehicle reliability. The engine’s design promotes a smoother driving experience with minimal vibration, enhancing the quality of steering and ride comfort.
For maintenance, we’ve learned through experience that adhering to a regular oil change schedule is pivotal. Typically, with engines like the 2.4L I4 F DOHC 16V, oil change intervals are recommended every 5,000 to 7,500 miles, but this may vary based on specific manufacturer guidelines and the type of oil used.
| Aspect | Guideline |
| Oil Change Interval | 5,000 to 7,500 miles |
| Regular Maintenance | According to the owners manual |
In terms of interior and noise, our aim is to ensure quality materials and fit and finish to provide a quiet and comfortable environment.
